Oskar the economist! From his attractive styling he is able to humidify a room up to 40m². Air is drawn through the water soaked filters and then the humid air is circulated through the room by way of a fane. The filters are pre treated with anti-bacterial agents to aid in the elimination of bacteria. There is a built in Hygrostat so you can not over humidify your room and an automatic cut off for when the tank is empty, saving electricity. The LED control lights can also be dimmed in 'night mode'. An optional Ionic silver cube is available to further prevent the growth of bacteria and germs.
